The Chinese study history, like any other competent military. They know our D-Day invasion survived only because of surprise, made possible because the Germans had only rudimentary radar and didnt see a thousand ships crossing the channel until they saw them with their own eyes. And they are not stupid enough to think they can pull off a D-Day style invasion in a high intensity intel environment, where every raft and rowboat will be seen a hundred miles away.
Airborne assault troops?
They require air supremacy for that.
Something they’ll not have.
